Abstract: In this talk, we introduce Stäckel separable coordinates on the covering manifolds Mk, where k is a rational parameter, of certain constant-curvature Riemannian manifolds with the structure of warped manifold. These covering manifolds appear implicitly in literature as connected with superintegrable systems with polynomial in the momenta first integrals of arbitrarily high degree, such as the Tremblay-Turbiner-Winternitz system. We study here for the first time multiseparability and superintegrability of Hamiltonian systems on these manifolds and see how these properties depend on the parameter k.
